Obviously, this is in the ‘proof of concept’ stage. No one is going to say, “it’s too arduous to remember to take my pills, so instead I’ll have them implanted and stand under a special light four times a day.” It’s not even clear to me who would be responsible for doing the triggering, the doctors or the patients themselves. Nevertheless, this technique does have tremendous potential, especially for patients who require long-term medication.
